SPECIFICATION forming part Of Letters Patent NO. 7245197, dated March31, 1903.

' Application filed August 17, 1900. Serial No. 27,195. (No model.)

To all whom it may concern:

Be it known thatI, SIEGFRIED G.MARSHUTZ, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, haveinvented certain new and useful Improvements inTrial-Frames for Oculists or Opticians, of which the following is aspecification.

My present invention pertains to improvements in trial-frames foroculists and opti- ,cians, the construction and advantages. of

which will be hereinafter set forth, reference being had to the annexeddrawings, wherein- Figure 1 is a perspective view of the frame as awhole,certain attachments being omitted; Fig. 2, a front elevation; Fig.3, a similar view, on an enlarged scale, showing the attachment of aframe carrying a series of triallenses; Fig. 4, a side elevation of thetriallens frame or carrier; Fig. '5,'a cross-sectional view on the line1 1 of Fig. 2; Fig. 6, a similar view on the line 2 2; Figs. 7, 8, and9, front, sectional, and rear views, respectively, of the nose adjlisting-piece; Fig. 10, a perspective view of a modified construction ofthe main frame or holder; Fig. -11, a rear elevation of a portion ofthedevice,showing the means for rotating the lens-holding cell; Fig. 12, asimilar view, partly in'section, illustrative of a modified means whichmay be employed for securing the vertical adjustment of the cells; Fig.13, a sideelevation of one of the cells, showing the beveled scale; Fig.14, a perspective view of the clamping device employed in connectionwith the construction shown in Figs. 1 and 2; Fig. 15, a sectional viewof the same; Fig. 16, a side elevation showing the trial-framein'working position and also illus trating a modified form of attachingmeans; Figs. 17, 18, and 19, detail views of the cellindicating devices;.Fig. 20, a rear elevation showing a modified form of the cellindicating and moving devices; Fig. 21, a similar view; Fig. 22, a faceview of the dial shown in Fig. 20; Figs. 23 and 24,-perspective viewsshowing modified forms of means for holding the frame in position; andFig. 25, a perspective view showing a portion of the frame asillustrated in Fig. 1, with a pneumatic band for securing the same tothe head of the patient.

a rubber or other hollow yielding body or the pnpilary adjustment of thelens holders or cells may be readily ascertained by the operator withoutbeing compelled to look into the patients face, to provide means wherebythe principal operations for adj usting a trialframe on the head of apatient may be accomplished from the side of the trial-frame, and. thusto one side of the patients head, without the operator being compelledto place his hands before the patients face, and also other objects andadvantages which will appear in the following description. Referringmore particularly to Figs. 1 to 9, inclusive, and 14 and 15, 1 indicatesthe main supporting-bar, having. hinged to its ends side bars or members2, said members 1 and 2 having secured to their inner or rear faces tube3, which may be inflated through a suitable valve or cook 4. The sidemembers 2 have secured to them a tubular slotted member 5, adapted anddesigned to receive attaching devices for a band or yielding strap 6,said attaching devices being shown in detail in Figs. 14 and-15. To eachend of the. strap there is secured an arm 7, havingdownwardly-projecting wings 8. A shoe-piece 9 of such diameter as topass within the slotted tubular member 5 is made fast to arm 7 by a studor post 10, and rising from 'said shoe near its outer end or in linewith the winged portion 8 is a threaded stem 11, which passes freelythrough an opening formed in arm 7. A thumb-nut 12 is mounted upon theouter end of stem 11, and after the shoe is entered in the tubularslotted member 5 and the parts brought to their adjusted positionthumb-nut 12 is screwed upon the threaded stem, causing shoe 9 to bearagainst the face of tubular IOO member 5 and U-shaped or winged portionof arm 7 to bear or clamp upon the outer face as is usual, being rightand left upon opposite formed upon the members 1 and 2 a comfort-- ableand ready fit of the frame upon the head of the wearer is insured, aswell as a firm reteution thereof in place. Instead of employing a strapformed in this manner a pneumatic band or tube may be used, asillustrated in Fig. 25. This band may or may not be adjustable. The factthat it is distended renders adjustment to a greater or less extentunnecessary. With any of the constructions it is advisable to so makethe band that its outer covering will be in the nature of a flexibletubeas, for instance, of velvet. This for the reason that the springs orother appliances which hold the trial-frame to the head will catch inthe patients hair. Either construction aifords'a comfortable method ofretaining the frame firmly on the head of the patient without thepossibility of the fastening devices catching in the hair.

To the front plate or member 1 or upon suitable brackets 14extending'upwardly in front thereof there is pivotally secured a tube15, in which is mounted a rod 16, Figs. 3 and 5, having formed thereonpinions 17, which mesh with racks 18, working in guides or ways 19,secured or mounted upon tubular member 15. Said racks 18 constitute a.support for a tubular member 20, journaled in the lower ends thereof andin which is mounted a threaded shaft 21, the threads of which,

sides of the center.

Cells or lens-holders 22, of any usual construction, are employed in theconstruction shown in Figs. 1, 2, 3, 5, and 6, though in practice therewill be used, in all probability, a lens holder or cell of a novelconstruction, as hereinafter set forth. It is to be understood, however,that either form of lensholder may be employed. The threaded nuts orblocks 23, formed at the upper ends thereof, work through slots formedin the tubular member 20 and are engaged and actuated bysliaft 21.Spring-arms 24 are secured at their lower ends to the cells or to thetubular memher 20 and serve as index-fingers or pointers, working overa. scale formed uponmember 15 in order that the pupilary adjustment ofthe cells may be readily seen and dete mined. To efiect this sameend-namely, the ready determination of the pupilary adjustmentthere mayalso be employed a scale or dial 25, (see Figs. 1, 2, and 3,) carried atthe outer ends of the shaft 21, which works in conjunction with fixedpointer or index-finger 26,

Shown as attached to one of the rack members 18.) Thisconstruction-is,advantageous from many points of view, as the operatorcan readily determine the pupilary adjustment without having to lookaround in front or into the face of the person undergoing treatment.

From the description thus far given it will be seen that the cells 22may be adjusted in a horizontal plane for pupilary adjustment, may beraised or lowered in a vertical line by the movement of shaft 16, andmay also be swung to either side of the vertical position by reason ofthe tubular member 20 being journaled in the lower ends of the rackmembers 18. Some of the various positions which the cells may assume areindicated in Figs. 5.and 6. In Fig. 5 the members 18 are shown in alowered position, with the cell in a practically vertical position infull lines and swung up out of the way, as shown in dotted lines. InFig. 6 the cells are shown in an elevated position with reference to themain frame of the device, and thrown forward in fulllines and rearwardlyin dotted lines, the two positions being, however, somewhat extreme inorder to accentuate the possibilities of adjustment of the apparatus.

In Figs. 1 3, and 4 there is illustrated a construction which I term anauxiliarylens attachment. It consists of a bar 27, slidably mounted in abracket 28, which is secured to the fixed member of the usual lens cellor holder. From said bar 27, at each end thereof, depend arms 29, andbetween said arms is secured a rod upon which are pivotally mounted aseries of lens-holders 30, containing suitable lenses of differentstrength. The connecting-arms of the frames 30 are preferably crooked,as shown, in order that the lenses may be thrown up in line with thelenses carried by the usual cell 22 without having anything projectingacross the lenses carried by the cell. It will be noted that the bar orrod 27 may be moved longitudinally through the bracket 28 and that anyone of the series of lenses carried by the frames 30 may be brought upin direct and close alinement with the lens or lenses carried by cells22. Ordinarily the auxiliary lenses will depend or hang down in theposition indicated in Figs. 1 and 3, where they will be out of the wayof the attendant or operator and will not hinder or obstruct the view ofthe pa tient in the least. By detaching the bracket 28 the auxiliarylenses and their carriers may be readily dispensed with and the frame asa whole lightened to that extent.

In Fig. 10 it will be seen that the front plate or member is not as longas shown in Figs. 1 and 2 and that the tubular supports 31 afford thelength necessary to secure a proper relation between the parts.

InFigs. 1, 7, 8, and 9 there is shown a detachable nose-piece, which mayor may not be used, as desired. When employed, it will IIO be usedsimply to secure the proper measurement for the nose-piece required forthe spectacle-frame and not to obtain proper adj ustment of the frameupon the patients head, as in the case of the trial-frames heretoforeconstructed. Upon reference more particularly to Figs. 7, 8, and 9 itwill be seen that it comprises two arms 32 and 33, hinged together, theouter ends of which are held or forced apart by a spring member 34. Theinner members or fingers 35 are provided with suitable holes adapted topass over pins'36 when the nose-piece is clamped upon the cross-bar ortubular member 20. The upper member 32 is provided with a-hollow stud37, through which passes a post 38, adjustably held therein by aset-screw 39. The lower end of the post is enlarged anil provided with ahorizontally-disposed opening, through which passes an arm 40, carryingat itsouter end a curved member 41, adapted to rest upon the nose of thepatient when the parts are adjusted to their proper position. Thisdetachable nosepiece constitutes one of the features of my presentinvention. As now constructed trialframes are usually held in place bythe nosepiece only and the total weight of the heavy front part of theold-style frame rests on the patients nose. The detachable nose-piece inthe present structure will only be used to measure the height of thenose for the purpose of making the final fit of the spectacles orglasses to be worn; but during the whole operation of testing thepatients vision the nose-piece .is not present, and consequently willnot oppress the patients nose, nor will it involve the carrying of theweight of the trialframe on the nose, since the frame is held upon thehead .by the means heretofore described.

-In Fig. 11 there is shown a construction wherein the movable member42of the cell or lens-holder may be actuated by a wormshaft 43,, acting inconjunction with acircular rack. 44, formed upon the periphery of thesaid member 42. There is also secured upon the worm-shaft 43 a graduateddial or disk 45, which acts, in conjunction with a fixed pointer 46, toindicate the degree of rotation of the movable member 42, so that thedegree of movement of said movable member and the lens carried therebymay be readily and speedily determined, and this without the necessityof the operator facing the patient. It will also be noted upon referenceto Fig. 13 that the face of the rotating member is beveled and a scaleformed thereon, as at 47. This beveled scale facilitates thedetermination of the position of the movable member of the lens holderor cell and may be used in conjunction with or independent of the dialor index 45, just referred to. g Y

In Figs. 17, 18, and 19 another form of indicator for the cell or lensposition is shown. It will be noted upon reference to said views thatthe movable member of the cell is provided'with a circular rack, whichin turn with a gear 49,

meshes with a pinion 48, said pinion meshing an indexplate or dial 50. Afixed pointer 51 shows the adjusted position the coll-frames arerotated.'

In Fig. 20 there is shown a device wherein the ordinary adjustment ofthe lens carried by the cell may be indicated upon a dial or scalecarried to one side of the cell proper;

the position of the lens last removed from the cell, so that theoperator may place the succeeding lens in the exact position occupied bythe one just taken out. Furthermore, it shows an indicator or pointer soarranged that the pupilary adjustment of indicated upon a suitable scaleupon "the frame. Referring niore particularly to said Fig. 20, 52indicates the inner movable member of the cell or lens-holder adapted tobe actuated by a worm-shaft 53, which shaft is carried by depending bars54. Shaft 21, as in the construction above referred to, is provided formoving the cells either to the right or left to secure the necessarypupilary adj ustment. lens-holder is designated by 55 and to it and oneof the depending arms 54 are secured arms 56, which form suitablesupports for disk or dial plate 57, over pointer 58, attached directlyto the operating or worm shaft 53. Surrounding and moveable upon thefixed. member 55 of the cell or lens-holder is a ring 59, provided withapointer 60, which has a set-screw working therein. The pointer 60 isadapted to pass over the scale upon. the fixed member 55, and aset-screw 61, mounted in said pointer, enables the operator to fastensaid ring 59 at any desired point to indicate the position of the lenswhich hasjust been removed, so that the lens to take its place may beput in the position occupied by the previous one.

In Fig. 21 an alternative construction is shown, wherein it will benoted that the fixed pointer (indicated by 62 works) in conjunction withadisk or index 63, secured upon the operating shaft 53.

In Figs. 23 and 24 there is illustrated a modified form of the mainframe, wherein instead of employing a strap to pass about the head, asin the former construction, the front plate 1 has hinged to it at eachend curved arms 64, adapted to conform in outline to the head of theperson. A pneumatic cushion 65 is preferably employed. To maintain theparts in'position, springs 66, coiled about the hinge, as shown in Fig.23, maybe employed, or flat springs 67, as shown .in'Fig. 24, may beused.

In Fig. 12 there is shown a form of suspending device for the cell,wherein instead of employing racks for elevating the cell a threadedstem or post 76 extends up from the cell through a slotted bar 77; Athumb-nut 78, screwed upon the upper end of the post, provides for thevertical adjustment of the made fast to and movable with l of the partsas the cells will be also, a separate indicator or pointer to show 9 Thefixed member of the cell or which works acell and at the same timepermits its longitudinal or pupilary adjustment toward the companioncell.

In Fig. 16 I have shown a modified form of holding device for the frame.Instead of employing the slotted tubular members 5, as in theconstruction illustrated in Figs. 1, 2, and 14, two straps or hands 79,preferably of the same construction as hand 6, are detachably connectedto the side members 2 by hooks or other suitable fastening devices 80.From the drawings it will be seen that the two bandsinsurea firm holdingof the frame upon the head of the patient.

From the foregoing description it will be noted that the invention issusceptible of many modifications, and I do not, therefore, desire tolimit myself in the broad and underlying principles to any particularformation or construction.

As before mentioned, the adjustment of the cells or lens-holders isuniversal-that is to say, they may be adjusted in a horizontal planetoward and from each other, may be moved in a vertical plane, and theymay also be swung backward and forward. This lat ter movement- -namely,swinging them forwardis of manifest advantage when it is desired toremove the testing-lenses out of the line of vision of the patient forany reason, and this without the necessity of removing the testing-frameor taking the lenses from the cells. Again, as pointed out, by havingthe index or scale for reading the pupilary adjustment arranged to oneside of the cells and at rightangles thereto--as, for instance, thedials or index-plates 25, 57, and 63-the pupilary adjustment may bedetermined with facility and without the necessity of the operator.standing in front or looking directly in the face of the patient. Thepointer formed by spring-arms 24 working in conjunction with the indexon the face of the main frame or cross-bar also afiords another readymeans of reading the pupilary adjustment, and the use of the beveledscale, as shown most clearly in Fig. 13, is also advantageous in readingthe correct position of the lenses within the cells. The employment ofthe scale or index to one side of the frame for indicating the positionof the lens or cell is of great advantage, thus doing away with thenecessity of constantly looking into the patients face while theexamination is in progress.

The use of the supplemental lens-holder in conjunction with the ordinarycells is advantageous for the reasons given, and while the constructionset forth is deemed the best in practice yet it is manifest that nowthat the idea has been suggested various means may bedemployed forbringing about the same on Having thus described my invention, a claimis-- 1.
